Product Family Description

  • Splits Input Image Into Two Paths Separated by 180°
  • Variety of Sizes and Broadband Coatings Available
  • Additional Right Angle Prism Options Available

TECHSPEC® 90° Specialty Mirrors are constructed from right angle prisms with a mirror coating on the two legs and an uncoated hypotenuse. The mirrored surfaces form a precise 90° angle, ideal for splitting an image from a single imaging lens onto two different cameras, or for combining two images onto a single camera.
